fantasio:~/tmp/linux-2.6.20$ fgrep CONFIG_LBD .config
# CONFIG_LBD is not set

Yes I said that. At least I did not notice it happen:) 
Reproduction seems easy. So I will try. 

I have some problem: I am not sufficiently familar with git!

I found http://www.kernel.org/pub/software/scm/git/docs/howto/isolate-bugs-with-bisect.txt
Is this the way to do a git-bisect?
